When I used the patch 2.4.18-15 to enable SMP support I could compiled
it. When running, the system often crashed with errors like:
Physical address in uninitialized region
panic: Segfault with no mm
I'm tracing myself and I can't get out.
When I use the latest patch 220.127.116.11, error messages above seldom
appear, but the system often freezes.
If I set processors = 2
UML can often boot. But it freezes when I run LMbench in it. I see there is
a process in the host almost occupies 90% of CPU time. It looks like that
the process is deadlocked or in an endless loop.
If I set processors = 4 or 16
Sometimes UML can boot. But quite often, it freezes during booting at
Initializing RT netlink socket
some other steps.
Does anyone have some ideas about it? Can anyone give me some hints how to
make it work stable.
